This is an activity about light and color. The lesson includes a demonstration to show why the sky is blue and why sunsets and sunrises are orange. Participants will use scientific practices to investigate answers to questions involving the color of...(View More) the sky, sunsets, the Sun, and oceans. This activity requires use of a clear acrylic or glass container to hold water, a strong flashlight, batteries for the flashlight, and powdered creamer or milk.(View Less)

Participants will experiment with ultraviolet light sensitive plastic beads, which are generally white but turn colors when exposed to UV light. Participants are informed about the nature and risks of UV light and are asked to be the scientist to...(View More) explore what types of materials keep the beads, and hence the user, safe from UV light.(View Less)

This is a challenge-based activity set designed to have students explore and research the Magnetospheric MultiScale Mission (MMS). Students will explore the purpose and relevance of the mission as well as the scientific methodologies. Activities...(View More) include application of the scientific method, problem solving strategies, research, collaboration, critical thinking and communication. Links to resources and appropriate web 2.0 tools are provided through a shared livebinder.(View Less)

This lesson is an introduction to the use of a magnetic compass. At a specific location, learners will locate an object using a compass, identify its bearing, and others will attempt to locate the object by only knowing the bearing reading and the...(View More) corresponding location where the bearing was obtained. Next, learners will develop a method for determining if a magnetic storm is occurring, and they will test this method using online information and a compass. This activity requires compasses and access to the Internet. This is Activity 5 in the Exploring Magnetism on Earth teachers guide.(View Less)

This is an activity about size, distance, and perspective. Learners will observe two objects of the same size placed at different distances, and they will observe two objects of different size placed at varying distances. This concept is then...(View More) related to how our Sun looks larger than all of the other stars in the sky due to Earth's proximity to it. This activity is from the Stanford Solar Center's All About the Sun: Sun and Stars activity guide for Grades 5-8 and can also accompany the Stanford Solar Center's Build Your Own Spectroscope activity.(View Less)
